`Application led May 4,11914. Serial No. 836,271.

To all whom t may concern Be it known that I, JAMES O. BLAKE, a` citizen `of the United States, residing at Gary,in the State of' Indiana, have invented a new and useful Improvement in Railroad- Ties, of whichthe following is a specification.

My objects are to provide an economical construction of railroad tie, and to provide `means on the tie, `integral therewith, for securing rails in place thereon.

Referring to the accompanying drawings, Figurel is a view in elevation of a tie oon-` structed in accordance with my invention, `a portion of the tie being` broken away, and the railsapplied to the tie shown in section. Fig. `2 is a planview of' one end of the tie showing a rail imposition thereon. Fig. 3 is an end view of the tie, showing by. a view in side elevationa rail positioned thereon; and Figa, a perspective view of one endzot the tie.

In carrying` out my invention I provide a pair of heads,ior chairs, 6, spaced apart from center to center a distance equal approximately to the `distance from center to center of `the rails to beused with the tie. These chairs may beof any suitable construction,

but I prefer toform them of steel members i of H-shape `in cross-section with upwardly converging ends as shown, aii'ording at their lower `flanges 7 relatively long seating sur- 'faces forming bearings ortheitie on the road-bed, and at their `upper flanges 8 relativelv short seating surfaces for the` rails. 'ine form off chair shown is especially desirable, as it maybe cut from a bar ot' steel without `any appreciable waste, and while presentingsuflieient bearing surfaces at `its upper' and lower portions for all practical requirements, involves the use of the mini-` mum amount of' material.

The chairs Gare secured together', preferably at their upper and lower' flanges 8 and 7, respectively, by bars 9 and 10, these bars beingpreferably `formed of steel and eaeh comprising a base-portion 11 formed with a strengthening rib 12 extending longitudinally: thereof'. rlihe bars 9 and 10 overlap, `at their bases 11, the flanges 7 and 8 of the chairs and are secured thereto as by rivets 13 passingthrough the bases 11 andthe flanges of the chairs which they overlap. The formof bar which I prefer to employ is of T-shane in cross-section, the ribs 12 of whichin the case of the upper bars 9 being preferably shorter than the base-portion 1l of these bars, and of suoli length that their ends, when the rails are applied to the ties in properly gaged position, `will reach a slight distance short of the webs or' the rails represented at 14. The ribs 12 oi the upper bars 9 are preferably recessed at their ends immediately above the baseportions 1l, as represented at 15, for receiving the inner flanges 1G of the rails 14:, the inner edges of these flanges bearing against the innermost walls of these recesses.

rlhe tie is provided with means for holding the rails 111 in place thereon, these means by preference, being formed integrally with the bars 9 and comprising lips 17 formed on the `ends of the base-portions 11 of these bars beyond the rails and adapted `to be bent upwardly and inwardly to overlap the outer flanges 1S of the rails and` cooperate with the recessed portions 15 of theibars 9 for clamping the rails in place on the tie.

Vhere the `rail-clamping means just `described are employed, the ties maybe disengaged from the rails by bending the luo's 17 upwardly and outwardly away from the flanges 1S, and as repeated manipulation of the lugs 17 in the event of repeated unfastening of the rail, might produce a weakening` of the lugs `17, I prefer to provide two sets of the lugs `17, formed by slitting the ends of the base-members 11 oi. the bars 9, whereby a reserve set `of these lugs is provided.

It will be understood from the foregoing that the chairs 6 are firmly held against undue displacement on the roadbed,lby means of the bars 9 and 10, which, by reason of their formation with ribs extending at angles to their base-portions, may be of coinparatively light weight and still present a high degree of resistance to stresses tending to flex them.

In the form shown, the ends `of `the ribs 12 of the bars t), at their recessed portions, form means for preventing the inner flanges 1G of the rails from rising, the end-portions of these ribs also serving as abutments 'for the inner flanges 1G of the rails;` and while it is desirable that the rails abut against the innermost wallsotI these recesses,` the abutment may, if desired, be between the ex.

i these ribs.

ktremeouter ends of these ribs and the webs of the rails 14, oragainst both portions of It .will be understoodfrom the lforegoing description that a tie constructed in accordance with my invention will be of comparaL tively light weight, but pOSSSSS 21 high degree-v V of rigidityv and stiffness and resstanceto stresses exertedfby va train passing over the rai-ls. Y W

. while I pieren to formthebars 9 and 10 or T-sliape form in orossfsection, itv will be 'readily understood that `any other suitable form of strengthening` rib may be employed yto permit relatively light weight bars to be used. l d
